Not possible just yet. There's some sort of oddity in the model format that prevents the models from being exported properly. However, keep an eye on this topic for further developments in the model format:

With Noesis, you can now preview and export the models from the 360 version of Marvel vs. Capcom 3 (and you'll need the textures from the PS3 version, since the 360 ones are sometime buggy) with the rigging nearly intact. It's a bit glitchy (and doesn't work for everything), but it works, nonetheless!

Here's a quick render of Tron's model. Had to use the "dizzy" face, since the eye textures won't export for some reason.

After open Blender and set the path of the python scripts (extend down the upper bar to see the options), go to file->import->meshasciiimporter (or something like).

Ta-da. You got it. If you want it for Max:

Export it in .FBX (or .obj) format (probably there are better formats to export it, i found this work). Open it in Max, wait it to upload (WAIT, because it looks that it crash, but in fact is loading), and...

I will get to that whenever I get around to porting Tron. It's gonna be bodygroup Hell, though. Drill arms, Servbot cannons, treads, propellers, and a bunch of other things that will all need to be set up properly.

Wish I could, but the exporter is broken for those. For some reason, they don't export with any rigging or UV mapping, so those will have to wait, unfortunately. Same thing with Taskmaster's weapons, for example. (Shield is missing UV mapping, and sword just won't export.)

Out of curiosity, which would be easier: making body groups or separate models entirely?

It'll be a while before I'll be working on Tron Bonne or the Gustaff (because of my clogged backlog of requests and whatnot). By that time, Noesis might have fixed the rigging errors when exporting, and I'll work on them then.

Dante, Amaterasu and Iron Man, are the ones i like to see, and Amaterasu would be easy to do, since she doesn´t have eyes at all, well, it has, but they are black. Iron Man has a lot of weapons and Dante :O, maybe my 2nd i want to see, but the third surely would be Deadpool, he´s funny saying somethings
I think that i hear this when he starts to battle sometimes:
"I wish to the ghost of christmas for: Kick your ass!" and the things he say when he won a battle, but still, a good character.
